Can i still treat it as whole deep beam (ht + hb + do) ? Or I shall treat the beam above opening with effective depth ht only to take the flexure @ opening area) ?
Supposed we have a long beam , there's an opening along teh span of the beam.
My question is how to calulcate the bendign moment capacity of the beam at the opening location.
1.) Does it still act as the deep beam with effective depth of hb + ht + do ?
2.) Or the part where the beam is on...
I am able to see all lines properly in dxf files. However , when I imported the dxf file into Etabs, some of the lines disappeared. How to resolve this? Tried to resave dxf files many times, problem persists. I am sure that I only have 3 layers in my dxf files, beam, wall and slab
Say that the d = 300, last peimeter of shear link required is at 700mm from the column face, the 1st shear link perimeter is at 0.5d = 150 from column face. Subsequent shear link at 300mm, 450mm, 600mm away from column (Radial spacing limit = 0.75d = 225mm) . now the question arises, Can i...
During the design of basement, why do we need to consider the uplift of the basement subjected to hydraulic uplift ?
When the excavation happen, watertable drawdown occur at the exacavted part.
When the excavation finished, the watertable already at the base, why the basement will be...
1.) Since you made the horizontal rebar as main rebar at top for both slab, For slab at the right, when you design the slab top bar , do you make the effective depth (center of rebar to base of concrete) shallower ? This will result in higher amount of rebar necessary ?
2.) I might as well...
Can you provide a sketch that how's its down at construction site usually? Extra horizontal top rebar with lap with which one? I have no idea at all... Thanks for your help
Say that I have a basic T10-200 bar top and bottom for both slab aforementioned. However, there’s extra T10-300 top horizontal top bar needed at the junction. In such case, extra T10-300 is added at the outermost top (T1) or inner top (T2) ? How can this extra T10-300 lap with existing rebar...
Thanks, so when the spacing of column is equally spaced in both direction, so the main bar direction doesnt matter?
How if the at the intersection of 2 slab, at the continuous part , slab 1 main bar direction is horizontal (T1), whereas for slab 2 , slab 2 secondary bar direction is horizontal...
In flat slab system, say that the total length is 48m x 24m, column with drop panel with spacing of 6m... In this case , main bar outermost top bar (T1) and outermost bottom bar (B1) should be parallel to the 24m , right?
I came across an example that main bar T1 & B1 is parallel to 48m...
Can someone help to explain the shape of the shear force diagram? Here’s a box culvert model subjected to UDL on top slab. The box drain is supported by pile below , which model as spring, the bottom slab is supported by line spring as well.
Here’s the result of the analysis. I found that in...
I understand that both LF ULS and LF ULS ovt represent the load factor for unfavourable action, the ULS LF selfweight represent the unfavourable action for selfweight.... However, the ULS ovt LF represent the favourable action or unfavourbale action for overturning ? Can you confirm on this ?
Is there anyway to overwrite the design to become column design ? I have assigned column at the designated location. However, it turned out that some of teh column design becamne beam design. That's weird , is there anyway to overcome this ?
